' This invention relates to changeablesi'gns or bulletin boards of the stationary type, and has forits main object theprovision of a sign board of this character having a{ series of detachable letter trays' which are indtvidually removable from the board, the letter trays having removable letters or indicia. i I

Another object of theinvention 3 is the I provisionof a sign board of the character mentioned having {letter trays detachably supported onthe board in a novel manner so that they may be very quickly and easily mounted in position orindividually re- '15moved from the board. v Other objects and advantages of the invention will be apparent from the foll0wing description and from the accompanying drawing, in Which- 1 Fig.1 is a front elevation ofa bulletin board embodying the present invention, part of the board frame being broken away;

Fig. 2 is a verticals ectionthrough the top of the beard on the, line 2+2 of Fig. 1 Fig; 3 is a section on the line of Fig. 1;

Fig. 4: is a section on the line i 4c'of Fig.1,and 1 I Fig.6 is a front view of one end ofa tray. The sign of the present invention is of the stationary type adapted tor the support of a numberof legends andindieia in such manner as to permit them to be readily changed; Bulletin boards or signs of the present invention are particularlydesirable in that theyv permit the words or phrases to be applied to removable trays Wherever this isfmost ,con-

venient, and then the trays may be very quickly applied toor positionedon the board.

The application .of the letters to the trays need not take place while oneis standing in front of the board,'which may be in a public place or in view of many observers,but-this operation can be done at a desk where one.

would not be interfered with norxconfused. The application ofthe traystoethe board, which is a comparatively simple operation and one in which confusion would not be likely, is then a very simple, matter even ,thesign'is inla public place and observed many. y

1 Referring to the drawing,the si-gn orbul letinboard'of the present invention embodies a main iback board or sign support desig hated generally 10 and a seriesof'trays 11 which s'upporta series of letterpieces 12. The back board or support is shown in the form of a rectangular sheet of-metal'ltof any suitablethickness and size. This" sheet is peripherally enclosed bya' frame 'l5wh'ich maybe of wood or other suitablelmaterial; eachsicle of this framepreferably having a slot15 which -re'ceivestheedge ofthe metal [sheet-'14 as shown in Fig. 2. *This sheet is prov lded along each side with aseriesof tray'supports or clips 16; As showninFig; 4

thesev clips may be integrally struck out" of the single sheet of metal forming the-back plate so as to provide "upwardly extending fingersl'? and longer downwardly extending fingers 18 which are spaced a little distance" awayvfromthemain plane of the'sheet 14' so that they mayreceivethe endsof theflet ter traysll; The verticaldistance between afinger 18 of one clip and the adjacent finger'l7 of an adjacent' 'clip is such thatthe tray may be inserted by moving it upwardly behind the depending finger 18 as far as it I will go, 'afterfwhich the lower sideiof the tray may be moved towards 'theplate' 14 clearing thetop ofthe finger 17', and then the I tray may be moveddownwardly so that it is supported on the bottom ofthe fi'nger 17 and retained thereby. Thus the trays may be individually applied to or removed fromthe board, the trays being supported in such a way that only slight relative movementbetween a tray and the board,'is necessary in mounting itin place or-in" its removal. In the mounting of the trays or during their removal, such operations being accomplished without using tools of any 'sort,the clips themselves are not disturbed as it is notin- V tended that they should be bent or-moved in any way. 1 I Each letter tray 11 comprises-a strip of suitable material, preferably sheet metal, having an upturned bottom portion which "is reversibly bent @Q to form a groove or and downward successive movements of said trays without alteration of said clips, a series of letter pieces detachably supported by said trays, and a frame surrounding said main back plate and retaining said trays against endwise movement.

5. A sign of the class described comprising a back supporting plate, a series of trays detachably supported in an individual manner on said plate, and a series of letter pieces individually supported'by said trays in a detachable manner, each of said trays comprising a sheet of metal bent up at its lower edge so as to form a crook receiving the lower portion of said letter pieces, and means struck out integrally from said trays adjacent each end of said trays forming finger pieces by which the trays may be handled.

In testimony whereof I hereto aflix my signature.
